BALLING-MACHINE.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed February 11, 1916. Serial No. 77,750.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. I, 1313.)

To all whom it may concern Be it known that I, ALEXANDER GROUND- WATER VVALLS, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Paisley, Renfrewshire, Scotland, have invented a certain new and useful Improvement in Balling-l/Iachines, for which I have filed application in Great Britain, dated Feb. 22, 1915, Patent No. 2803, of which the following is a specification.

This invention relates to balling machines of the automatic type, and has for its primary object to provide for automatic control of the drag on the delivery bobbins in balling such material as heavy or hard twine and the like, which requires to be pulled off a'rotating bobbin.

The invention is illustrated in the accompanying drawings in which there is shown a sectional elevation of the top part of a balling machine showing the invention as applied to a well known type of balling machine.

As shown in the drawing, the bobbin 1, containing the material to be wound, is held on the revoluble sleeve 2 of the creel peg 3 by collapsible compression springs. The framework of the creel stand 4 supports the creel peg 3, and also carries a bracket 5, having a pin 6 on which is fulcrumed the lever 7 carrying a drag shoe 8, so shaped as to make line contact as distinguished from point contact with the twine while it is being unwound. The yarn 9 (twine) is pulled from the bobbin 1 around a roller 10 through the usual flier spindle 11 through the flier guide eyes 12, and is wound into ball form on the ball spindle 13.

The pressure of the drag shoe 8 on the surface of the yarn is regulated by the adjustment of a nut 14 on a screw 15 controlling the extension of a helical spring 16 attached to the lever 7 carrying the shoe 8. As the drag shoe bears on the surface of the yarn, whether the bobbin be full or nearly empty, and the bobbin is mounted on the revoluble sleeve 2 of the creel peg, variable friction due to faulty (not round) holes in the bobbin is thus avoided, and a practically even tension is obtained.

The drag shoe 8 is formed with inclined ends so that, when the operator removes an empty bobbin, the inner flange of the bobbin comes in contact with the inner inclined surfaceof the drag shoe 8, and, by virtue of the inclination of the contacting surface, the shoe rides over the flange of the bobbin.

On replacement of the empty bobbin by a full bobbin, the outer inclined surface of the drag shoe engages the inner flange of the bobbin and no material resistance is oflered to the endwise movement of the bobbin. Fulcrumed on the pin 6 of the bracket 5 is a momentum brake lever 17 which is normally held out of contact with the lever 7 and is liberated when the machine knocks off, so as to fall on the lever 7 and impart greatly increased pressure to the drag shoe 8, whereby a strong braking action is applied to the revolving bobbin. The braking action, being added to the winding tension of the yarn, absorbs the momentum of the driving shaft, so that overrun of the rapidly rotating bobbinvand consequent slack yarn between the bobbin and the flier is prevented.

The rock-shaft 34 carries a lever 44 which through the medium of a connecting rod 45, lifts the brake lever 17 against the action of a weight 46, and, during the period of winding the brake lever 17, is maintained in a position clear of the drag shoe lever 7.

When the shaft 34 is permitted to rock, the lever 44 and connecting rod 45 permit the brake lever 17, actuated by a weight 46, to apply extrapressure on the lever 7 and the drag shoe 8, and thus absorb the momentum of the driving shaft and the bobbin 1.

The connecting rod 45 passes freely through a slot in the. lever 17, and, when the shaft 84 is rocked to lift the lever 17, adjustable nut 48 on the connecting rod 45 engages .the lower face of the lever 17. W hen the connecting rod 45 falls, the nut 48 falls such a distance that, no matter how small a quantity of yarn may be on the b0bbin 1, the drag shoe will be pressed against it by the lever 17 actuated by the weight 46.

What I claim is 2- In an automatic balling machine, the com- 100 bination with a'bobbin carrier sustaining a shoe is caused to bear with increased pres- 10 bobbin from which the yarn is unwound, of sure on the yarn to arrest the bobbin.
